Module 2 Flashcards
Neurons
Allow communication throughout nervous system and body.
Neurotransmitters
pass from one synapse from to another. emotions and behavior are influenced
Cell body
energy is generated and info is collected for transmission to other neurons.
Synaptic receptors
embedded in the membranes of dendrites to receive chemical messages from the terminal of other neurons
Dendrites
receive chemical messages from other neurons.
Terminal
Chemical communications are sent out to other neurons here.
Axon
conveys info from the cell body to other neurons within the nervous system
Myelin Sheath
Speeds the transmission of neural impulses
Nucleus
Energy for cell is generated and waste products are eliminated.
Central Nervous System
Organizes and interprets the information from peripheral nervous system. Sends commands back to take actions
Brain
control system
Spinal cord
Relays messages to and from brain
Peripheral Nervous system
Connects the spinal cord to the body
Autonomic Nervous System
Controls involuntary actions
Parasympathetic Nervous system
Returns body to resting state after arousal
Sympathetic Nervous system
Arouses body to prepare for actions
Somatic Nervous System
Regulates voluntary motor actions
Forebrain
seat of thought, memory, decisions, planning, personality and emotion
Midbrain
Conveys visual and auditory information from spine to forebrain
Hindbrain
Controls bodily functions vital to life; contributes to regulation of sleep/
wakefullness
corpus callosum
connect left and right hemispheres of the brain
limbic system
regulate mood, emotion, memory and basic desires like thirst and hunger
Thalamus
gateway to higher functions
cerebral cortex
4 lobes. interprets sensory information, controls voluntary movement, home of higher cognitive processes.
occipital lobe
processes visual information
parietal lobe
processes sensations of heat, cold, pain and informs placement of limbs
Temporal lobe
Processes auditory information
Frontal lobe
primary motor complex. deliberate movements are planned.
Endocrine system
System of glands and hormones they produce
behavioral neuroscience
studies the neural basis of behavior. Study the entire nervous system, not just brain
cognitive neuroscience
Focuses on the human brain to reveal the neural basis of cognition and emotion.
gene-environment correlation
When a person’s environment is correlated with their genotype.
Active gene-environment correlation
When a person actively seeks out particular kind of environment
Reactive gene-environment correlation
When an individual reacts to their child in a way that creates a correlated environment
